Beamformer — Beamforming ist eine Methode zur Ortung (als Positionsbestimmung) von Quellen in Wellenfeldern (z. B. Schallfeldern). Entsprechende Vorrichtungen werden auch akustische Kamera oder Mikrofonarray genannt. In der Akustik wird Beamforming meistens… … Deutsch Wikipedia
Adaptive beamformer — An adaptive beamformer is a signal processing system often used with an array of radar antennas (or phased array) in order to transmit or receive signals in different directions without having to mechanically steer the array.The main distinction… … Wikipedia
Null-steering beamformer — Null Steering is a method of beam forming for narrow band signals where we want to have a simple way of compensating delays of receiving signals from a specific source at different elements of the antenna array. In general to make use of the… … Wikipedia
Beamforming — is a signal processing technique used in sensor arrays for directional signal transmission or reception. This spatial selectivity is achieved by using adaptive or fixed receive/transmit beampattern. The improvement compared with an… … Wikipedia
